Microwave plasma source

In a microwave plasma source, a tubular magnet portion has a first opening end and a second opening end. The first opening end has a first polarity, and the second opening end has a second polarity. The tubular body is surrounded by the tubular magnet portion. A first magnetic circuit portion closes the first opening end. A second magnetic circuit portion is disposed opposite to the first magnetic circuit portion. The second magnetic circuit portion has a first opening part. An antenna penetrates the first magnetic circuit portion, is introduced to a space, and supplies microwave power to the space. The nozzle portion has a second opening part that has a smaller opening area than the first opening part and communicates with the first opening part. When an inner diameter of the tubular body is represented by a (mm), and a microwave cutoff wavelength of the microwave power being supplied to the space is represented by λ (mm), the microwave plasma source is configured to satisfy a relational expression λ>3.41×(a/2).

Method and apparatus for the generation, heating and/or compression of plasmoids and/or recovery of energy therefrom
09741457 · 2017-08-22 · ·

Method and apparatus for heating and/or compressing plasmas to thermonuclear temperatures and densities are provided. In one aspect, at least one of at least two plasmoids separated by a distance is accelerated towards the other. The plasmoids interact, for instance to form a resultant plasmoid, to convert a kinetic energy into a thermal energy. The resultant plasmoid is confined in a high energy density state using a magnetic field. One or more plasmoids may be compressed. Energy may be recovered, for example via a blanket and/or directly via one or more coils that create a magnetic field and/or circuits that control the coils.
